Product Description

The Aeromotive 15678 AN-10 Fuel Line Block is a precision-machined fuel system accessory engineered to split a single AN-10 fuel feed into two AN-08 outputs for parallel distribution in performance fuel setups. Constructed from billet aluminum with a durable black anodized finish, this distribution block offers strength and corrosion resistance while maintaining a sleek, professional appearance.

With one AN-10 male inlet and two AN-08 male outlets, the 15678 simplifies routing fuel to dual rails, injector bungs, or multiple regulators without the need for complex adapters. Its free-flow internal design helps preserve fuel pressure and minimize turbulence, supporting consistent delivery in EFI and other high-flow applications. The compact size allows flexible installation in confined engine bays or fuel bays where space is limited.

This universal distribution block is ideal for custom performance builds, dual-rail EFI systems, and high-flow pump configurations. Always verify that your chosen AN-08 line sizes and hose assemblies match your specific fuel system requirements before installation. Proper sealing and torque on all fittings are recommended to ensure leak-free operation in high-pressure fuel environments.
